Good road but spoilt by over zealous traffic cops who are out to catch bikers. The workers on the ferry can be good for info on the police presence.
not done this section b ut have done the bit round Loch Fyne and Inverary, then up the coast to Oban - that entire trip is absolutely stunning. Must come here more often.......
This road suffered for a long time from a poor surface for half of its distance to Strachur. This has now been sorted, so no nasty bumps or the shakes. It used to be my main rout to all the other roads and was always a nice warm up. I even go out of my way now to sample its delights. For some added fun try a loop by taking in the B836 to colintive and then back to strachur. This is single track but fun.
For those of you touring Western Scotland and wishing to by-pass Glasgow and start the scenery show as early as possible: Take the Gourock/Dunoon Ferry from Gourock (just before Greenock on the A78 coast road) Ferries run every hour and it's a twenty minute crossing. Once on the other side of the water carry on northbound. The roads are quieter and even more beautiful than those upto there. Take the A815, which runs along the banks of Loch Eck to a T junction on the banks of Loch Fyne. Turn right, northbound, to another T junction on the A83. Turning right will take you to Loch Lomond (and the tourist traffic) Turning left will carry on around Loch Fyne into Inveraray. If you want to head north, take the A819, which is a narrow right turning just into Inveraray and takes you through Glen Aray, along Loch Awe, to a T junction on the A85, halfway between Tyndrum (for GlenCoe) and Oban (for the coast road). Have fun!
